To (0% whom it may concern:

Beit known that I, JOHN L. MESKER, a citizen of the United States, and aresident of St. Louis, Missouri, have invented certain new and usefulImprovements in Windows, of which the following is a specificationcontaining a full,'clear, and exact description, reference being had tothe accompanying drawings, forming a part hereof.

My invention relates to an improved window, and more particularly to awindow wherein the frame and sash are constructed of sheet metal,thereby providing a perfectlyfireproof construction.

My invention consists in certain new and novel features of constructionand arrangement of parts, that will hereinafter be fully shown,described, and claimed.

In the drawings, Figure 1 is a vertical section taken through the centerof a windowframe of my improved'construction, the sash and insertiblepanel being removed from said frame. Fig. 2 is a perspective view of theinsertible panel made use of in carrying out my invention. Fig. 3 is anenlarged detail view, partly in section, of the upper left-hand cornerof my improved window-frame. Fig. 4 is a vertical section similar toFig. 1 and showing the upper and lower sash in position in thewindow-frame. Fig. 5 is a horizontal section taken approximately on theline 5 5 of Fig. 4.

In the construction of my improved Window-frame the sill of the frame isconstructed of a single sheet of metal 1, that is bent into the form ofan ordinary sill, having an inclined top 2, and the space within thesillis preferably filled with cement 3 or analogous material in order toprevent the top of the sill from becoming dented. The sides 3 of thewindow-frame are each composed of a single sheet of metal bent intoapproximate rectangular form in cross-section, and the seam or jointformed by the meeting ends of the sheet of metal forming each side islocated at the center of the outside wall of each of the sides of theframe, as indicated by 4. Extending into each side member from thisjoint 4 is a plate 5, that divides said side members into twocompartments, the same being for the reception of the sash-weights 6.The front portions of the side members 3 are extended toward oneanother, as indicated by 7, beyond the plane occupied by the insidewalls of said side members, and shoulders 8 are formed-between saidportions ,7 and the flat inside walls 9 of said side members. These flatinside walls 9 are divided into two slideways for the upper and lowersash by the vertically-extending grooves 10 and 11, which are formed bybending the metal of the inside walls 9 inwardly, and said grooves vextend from the sill 1 to the top of the win dow-frame. The spaces orways between the shoulders 8 and the grooves 10 are occupied by thestiles of the upper sash of the window, and the space or ways betweenthe grooves 10 and 11 is occupied by the stiles of the lower sash. Thesheet metal or material 1 of which the sides of the frame areconstructed is cut away or removed from between the grooves 10 and 11the entire distance be tween the top of the sill 1 and a point justabove the plane normally occupied by the top of the upper rail of thelower sash, which space is indicated by the numeral 12. Formed throughthe inside walls of the sides of the frame and in the upper portions ofthe ways in which the sash move are the apertures 13, through which thesash tapes or cords pass, and arranged on the rear sides of the walls 9immediately back of these apertures 13 are pulleys 14, over which saidtapes or cords travel.

The top 15 of the window-frame is constructed of a single piece of sheetmetal bent into approximate rectangular form in crosssection andprovided in its bottom wall with a groove 16, which is formed by bendingthe sheet metal upwardly, and which groove is in alinement with theshoulders 8, formed in the inside walls 9 of the side frames.

The insertible members 17, that are adapted to fit in the spaces 12,comprise single sheets of metal, having their side edges bentrearwardly, as indicated by 18, and then bent forwardly, as indicated by19, thus forming narrow grooves 19 that when the insertible members arein position form continuations of the grooves 10 and 11. Each insertiblemember is provided with a vertical rib'20, that is formed by bending thematerial of the member outwardly, these ribs being for the purpose offorming guides or parting-strips for the lower sash. Each insertiblemember is provided at its lower end with a laterallybent lip 21, that isadapted to rest on top of the sill 1, and in said lip is formed anaperture 22, through which may be passed a screw or rivet for fasteningthe insertible piece in proper position.

The upper sash of my improved Window has its top rail 23, stiles 24, andlower meeting-rail 25 all formed of sheet metal bent into approximaterectangular form and of the same contour as is the corresponding partsof an ordinary wooden sash, and the inner walls of all of said membersare provided with grooves, such as 26, which receive the edges of thepane of glass 27. The top outer corner of the top rail 23 is providedwith a con tinuous rib 28, formed by overlapping the meeting ends of thesheet of material of which said top rail is formed, and said rib isintended to seat in the groove 16 when the top sash is moved to itsupward limit of movement. The inner and outer corners of the stiles 24of this upper sash are provided with ribs 29, formed by overlapping themeeting edges of the sheet of material of which said stiles are formed,and said ribs 29 engage and ride in the grooves 10. The outer corners ofthe stiles 24 are provided with ribs 30, formed by bending double thematerial of which said stiles are formed, which ribs ride directlyagainst the shoulders 8, formed in the inside walls 9 of the side frames3. The lower rear corner of the meeting-rail 25 is extended slightlybeyond the vertical plane occupied by the grooves 10, as indicated by31, and the top side of this extension is formed on an angle ofapproximately forty-five degrees, as indicated by 32. The lower sashcomprises the lower rail 33, stiles 24, and upper meeting-rail 35, allof which rails and stiles are formed of sheet metal and of the sameapproximate contour as are the corresponding parts of an ordinary woodensash. The outer corners of the stiles 34 are provided withvertically-arranged ribs 36, formed by bending double the endsof thematerial of which said stiles are formed, which ribs occupy and ride inthe grooves 11 and the corresponding grooves 19 of the insertible member17. The opposite corners of the stiles 34 are provided with the integralribs 37, formed by bending double the material of which said stiles areformed, which ribs engage against the ribs 20, formed integral with theinsertible members The outer up er corner of the meetingrail 35 isextended: as indicated by 38, and the under side of said extension isformed on an angle of approximately forty-five degrees, as indicated by39, and in opposition to the angularity of the top 32 of the extension31. This arrangement draws the meeting-rails 25 and 35 together when thesash are closed and forms a very thorough air, dust, and water proofjoint.

The lower sash is provided with a pane of glass 40, which is seated ingrooves formed in the rails and stiles of said lower sash. Suitabletapes or sash-cords 41 are connected to the outer faces of the stiles 24and 34 and pass from thence through the apertures 13 over the pulleys 14and are secured to the sashweights 6 in the usual manner.

The spaces 12 are formed and the inserti ble members 17 constructed inorder to get the sash-weights into proper position and also in order toproperly position the upper and lower sash and to maintain the same inthe window-frame without the use of parting-strips, stops, and screws.

This arrangement, besides forming a verycomplete fireproof window,readily enables a person to remove the sash quickly and easily wheneverit is desired to clean the glass in said sash.

- To assemble the window or to position the sash in the window-frame,one side or stile of the lower sash is inserted through the space 12until the opposite stile can be swung into the vertical plane normallyoccupied by said lower sash, and then said lower sash is so shifted andmanipulated as that the ribs 36 and 37, that project outwardly from thesides of the stiles, occupy the grooves 10 and 11. Said lower sash isnow elevated to its limit of movement or until the meeting-rail 35engages the top 15 of the window-frame. The sash-weights 6 are nowconnected to the tapes or window-cords that are secured to said lowersash and that pass through the apertures 13 and over the correspondingpulleys 14. One side or stile of the upper sash is now inserted throughthe space 12, and the opposite stile is then moved over until the rib 30on said opposite stile engages against the shoulder 8 and the rib 29occupies a position in the corresponding groove 10. Then the stile thatwas first inserted through the space 12 is now moved forward until itsribs 29 and 30 are engaged, respectively, in the groove 10 and againstthe shoulder 8, and said sash is now elevated to the top of thewindow-frame. The ta es or cords 41 and weights 6 are now fitte to saidupper sash, and the insertible members 17 are now inserted. Thesemembers are slightly longer than are the spaces 12 in order that the topedges of said members will overlap the lower edges of the inside walls 9just above said spaces 12, and when said members 17 are inserted thegrooves on the outer edges of said members are fitted into the lowerhalves of the grooves 10, while the grooves 19* on the inner edges ofsaid members 17 occupy positions immediately below the grooves 11. Theinsertible members are now secured in place by screws or rivets passingthrough the apertures 22 of the ears 21, and, if desired, the upper endsof said members may be secured to the inside walls 9 of the side frames,although I have found in practice that it is not absolutely necessary tofasten the insertible members at their upper ends. After the members 17have. been correctly positioned the lower sash is drawn downwardly, andin so doing the ribs 36 will travel in the inner pair of grooves 19,while the ribs 37 will bear directly against the ribs 20, formedintegral with said members 17. To remove the window-sash from the frame,the operations just described are reversed, and it will then be seen howI have provided a window wherein the sash can be very readily removedfor the purpose of washing the glass carried by the sash, and it is notnecessary to remove any parting-strips, plates, or fastening devices.

y improved window when properly constructed and assembled is air, water,dust, and fire proof and is very simple and durable.

I claim In a window ofthe class described, a frame constructed of sheetmetal and having the inner walls of the lower halves of the sides cutaway to allow for the insertion of the sash when assembling the window,there being vertical grooves formed in the inner walls of the upperhalves of said sides, insertible members fitted into the cut-awayportions and having vertical grooves formed in their edges to coincidewith the grooves in the sides of the frame, a lip integral with thelower end of each insertible member whereby the same is fastened to thewindow-frame and sash fitted into the window-frame, Which sash areprovided with ribs on the sides of their stiles, and which ribs operatein the grooves formed in the sides of the frame and in the insertiblemembers and the adjacent faces of the meeting-rails of the sash beingbent so as to form overlap ing ribs having oppositely-arranged inclinefaces which tend to draw the meeting-rails of the sash together whensaid sash are closed, substantially as specified.

In testimony whereof I have signed my name to this specification inpresence of two subscribing witnesses.
